Scientists at the University of Hawaiʻi at Mānoa's Institute for Astronomy will explain these and other phenomena at the Institute for Astronomy's annual open house on Sunday, April 10, from 11 a.m. to 4 p.m. located at 2680 Woodlawn Drive in Mānoa. Admission and parking is free.

There will be activities for both children and adults: make a sundial or a comet, observe sunspots with a telescope (weather permitting), launch a bottle rocket, or listen to talks about black holes, the search for habitable planets around other stars, and the latest discoveries by NASA space missions to comets.

Attendees can also get their face painted with a star or planet, see a planetarium show, or check out the 3-D astronomical image gallery.
